Active clinical trials for "Acute-On-Chronic Liver Failure"

Safety and Efficacy of Mesenchymal Stem Cell Transplantation for Acute-on-Chronic Liver Failure

Mesenchymal stem cells (MSC) has been reported to improved outcomes of acute-on-chronic liver failure(ACLF). More randomization controlled studies are needed to confirm the effect of MSC treatment for ACLF. This study aimed to investigate the efficacy of mesenchymal stem cells in ACLF patients. This study is an double-blind multicenter randomized and placebo-controlled study. Patients with with ACLF will be randomly assigned to receive MSC treatment (experimental) or standard medical treatment (control). Three times of MSC infusion (0.1-1x10E6cells/kg body weight) via peripheral vein will be given to the experimental group (once per week). The primary outcome is 12 week mortality. Secondary outcomes are clinical remission rate and changes of liver function indices and liver function scores.

In the past ten years, the extracorporeal liver support system has been widely used in clinical practice as a first-line treatment of liver failure. Plasma exchange (PE) can remove toxic substances in ACLF patients, reduce liver damage, and replenish coagulation factors, albumin and immunoglobulins, thereby improving the liver's microenvironment and accelerating liver regeneration and functional recovery. The ACLF study showed that PE can improve the symptoms of patients and improve the short-term prognosis of patients, but there are still studies showing that PE does not significantly improve the short-term prognosis of patients. Therefore, the therapeutic effect of PE on ACLF is still controversial. We consider that some people may benefit from plasma exchange, and new indicators are needed to guide disease stratification treatment. Our multi-center prospective data show that plasma exchange has a tendency to improve survival in ACLF-2. After stratifying with ADP inhibition rate in ACLF-2, patients with ADP inhibition rate greater than 30% will be treated 28 days after PE treatment. The prognosis is improving. Therefore, we consider that PE is expected to reduce the mortality of patients with ACLF 2 with an ADP suppression rate greater than 30%, but prospective large-sample clinical studies are still needed.

Primary Objective To evaluate the efficacy and safety of 72 hour NAC treatment regimen in the management of ACLF Secondary Objective To evaluate the six weeks mortality and length of hospital stay in ACLF patients treated with NAC Randomized, Double blind pilot study of IV N-Acetyl cysteine for the treatment of ACLF. Participants will be randomized into intervention and control arm using block randomization by computer generated random numbers. Efficacy will be assessed by clinical improvement in symptoms and signs of decompensated chronic liver disease (CLD). To assess safety degree of adverse reactions will be observed. Periodic assessments until 28 day will be done consisting of Physical exam, safety assessments, vital signs and lab tests. Dose of Drug: 72 hour regimen consisting of three doses of intravenous N-Acetyl cysteine will be used for a total dose of 300mg/kg. Number of Patients: 100 Accrual period: 15 months

The study is done with the aim of finding the association between the bilirubin and bile acids / DAMPS molecule with organ failures and sepsis in the patients with acute on chronic liver failure . in this study there are 2 parts in the first part people who satisfy the eligibility criteria will be recruited and blood samples will be taken and above mentioned molecules will be analyzed and association ,if any with occurrences of organ failures / new onset sepsis will be analyzed . In the second part of the study the patients who meet the criteria will be randomized to either receive standard medical therapy or with either haemoperfusion or therapeutic plasma exchange with standard medical therapy . blood samples will be taken and stored, bile acids (primary and secondary bile acids, bilirubin and damps molecules will be analysed .the patients are followed for 90 days , then statistical analysis will be done to find the association with organ failures and new onset sepsis .

The AIM of the study is to study the efficacy of intravenous albumin and standard medical treatment as compared to standard medical treatment alone in ameliorating/preventing SIRS and improving survival at 28 days .The project will be conducted in ILBS from august 2018 to December 2019Concept is to understand the immunology, pathophysiology and effects of albumin in the management of ACLF for betterment of the patient's condition and early recovery. All ACLF patients will be included as per the inclusion and exclusion criteria , after taking informed consent from the patient or their relatives. Will be evaluated for the possible risk factors for the development of SIRS/sepsis in ACLF patients and possible beneficial factors for resolution of SIRS /sepsis in ACLF patients. The effects of albumin administration as per this protocol versus standard medical treatment alone will be reviewed If patient develops allergic reactions to albumin, fluid overload, albumin will be stopped and patient will be treated accordingly to medical condition.

ALF (ALF) is defined by three criteria: (1) rapid development of hepatocellular dysfunction (jaundice, coagulopathy), (2) hepatic encephalopathy, and (3) absence of a prior history of liver disease. Interval between onset of acute hepatic injury (jaundice) and onset of liver failure (encephalopathy with or without coagulopathy) in such patients (icterus-encephalopathy interval; IEI) has been described to be between 4 weeks (Indian definition) to 24 weeks (AASLD-ALF study group). Further, due to the diverse natural course, ALF has been sub-classified as hyperacute (IEI ≤ 7 day), acute (IEI ≤ 4 weeks) and sub-acute ALF (IEI ≥ 5 week to ≤12 weeks) by British authors.

The patients with ACLF having Ascites who require ascitic tapping will undergone ascitic tapeither under albumin cover alone or with midodrine. The patient will be monitored for complication and changes of PICD. Study analysis will be done with primary objective being reduction in incidence of PICD.

Double-blind placebo randomized controlled trial evaluating the clinical efficacy of allogenic bone marrow derived mesenchymal stem cells in cirrhotic patients with acute-on-chronic liver failure

Acute-on-chronic liver failure (ACLF) is a syndrome that has recently been recognized as encompassing acute deterioration of liver function in patients with pre-existing chronic liver disease. It is associated with multi-organ failure and a high risk of short-term mortality. Thrombocytopenia is common in ACLF. In addition, the function of platelet is also compromised according to our previous data. The aim of this study is to explore whether platelet transfusion could reduce the short-term mortality rate of HBV-related ACLF. This is a single center, open labeled randomized controlled study. There are two arms. Subjects who is assigned to platelet transfusion group will receive both platelet transfusion (9 times/4 weeks, 1 unit each time) and standard medical treatment. While those in standard medical treatment group will receive standard medical treatment only. The major endpoint is 28-day transplant-free mortality rate.
